DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for connecting and fixing a pipe member and a bar member to each other so as to be freely slidable and slidable, and for example, supports a table member of a wheelchair user in a wheelchair. Connecting member, such as a pipe member or a bar member, for connecting and fixing a support bar member constituting a table support device for a vehicle to a pole portion of a vehicle body of a wheelchair.

[0002]

2. Description of the Related Art There have conventionally been proposed a large number of cross-connecting devices for connecting pipes, rods, and the like of this type such that they intersect at an arbitrary angle. For example, a pair of clamps, which are basically U-shaped and hold each connected member such as a pipe member and a bar member, are connected to each other so as to be freely swingable and swingable. It is used for cross-connecting pipe materials, such as pillars and beams, and bars of various workpieces.

[0003]

Such a conventionally proposed cross connector has a problem that the pipe material is bulky in weight,
Because of its load-bearing capacity for cross-connecting bars, etc., its own weight is considerable, and it is firmly connected by fastening tools etc. in consideration of stability at cross-connection It has become. For this reason, it becomes quite large and has a bad appearance, and it is not only troublesome for those who are weak but also to loosen the connection angle and position if there is no tightening tool etc. Was also very difficult.

On the other hand, the present inventor has been engaged in trial production and improvement of wheelchairs and other various welfare tools for many years. It has been demanded that keyboard operations and the like can be performed while the user is in a wheelchair. For this purpose, a table support device for a wheelchair for holding books, keyboards, and the like has been proposed. This table support device is provided with a pillar post made of pipe material, which is located at a lower end side of an armrest arm portion of a wheelchair and is attached substantially vertically to a pole portion of a vehicle body connected to a front small wheel, and a pipe which is horizontally attached to the pillar post. It is composed of a support bar made of a material and a table member fixed to the support bar. Then, the armrest arm portion and the support post are used, and the cross connection means for cross connecting the support post and the support bar is incorporated and used.

[0005] However, when the cross-connecting tool including the above-mentioned clamp tool is used as the cross-connecting means such as the support post and the support bar in such a table support device or the like, it becomes large and obstructive as described above. Is complicated, and it is difficult to change and adjust the mounting mode and the position corresponding to the difference in table position, height, inclination, etc., depending on the wheelchair user.
In addition, since the cross connection points between the connected members are not sufficiently reinforced, it is not possible to prevent the cross connection points from being inadvertently dropped due to a load applied to the connected members due to, for example, a user leaning on a table. Furthermore, when a wheelchair user gets in or out of a wheelchair, getting on and off while avoiding the table located in front of the wheelchair is troublesome for the user and requires extremely hard work for the disabled. Become. For this reason, the clamp itself as the cross connection between the support post and the support bar is slightly loosened and the table itself is rotated and retracted in the horizontal direction. At this time, the cross connection also allows the table to rotate vertically. Therefore, if the load of the article placed on the table surface is large, the table itself may slide down in the downward direction. Therefore, it is necessary to ensure the user's hand operation, which is very inconvenient.

Accordingly, the present invention has been made in view of the above-mentioned various circumstances, and has a very simple mechanism for reliably cross-connecting various connected members such as pipes and rods. It is easy to handle even those who are not capable of performing angle adjustment and position adjustment, etc., and can easily handle it.Moreover, when the cross connector itself is used as a table support device for a wheelchair, Not only can the table itself be rotated and retracted in the horizontal direction so that it is not inconvenient for the user to get on and off, but also the table can be prevented from inadvertently sliding down, etc. Can be reinforced, and it can be used not only as a component of the table support device, but also as a versatile member / device for cross-connection such as pipes and rods of this kind. It is an object to provide by the pipe which shall be able to use even the cross connecting device such as bars.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes connected members P1, P2 such as pipes and rods which cross each other.
It is a grip-shaped holding member basically formed in a U-shape, which is mounted so as to hold each of them, and these holding members 1A and 1B are combined in a pair to form two connected members P1 and P2. They are slid and connected at any angle and position.

The holding members 1A and 1B themselves are, as shown in FIG.
Left and right holding pieces 3A, 3B located on the sides of the connected members P1, P2 and facing each other at the ends of the contact portions 2 that are curved so as to abut the outer peripheral surfaces of the connected members P1, P2. A bolt insertion hole 4 is formed in each of the holding pieces 3A and 3B, and a non-slip portion 5 having a corrugated shape is formed on the outer surfaces of the holding pieces 3A and 3B. Anti-slip part 5
The clamping pieces 3A and 3B are formed on the outer surfaces of the clamping pieces 3A and 3B in a radially uneven shape with the bolt insertion hole 4 as a center, and are similarly combined with other clamping members 1A and 1B.
When the outer side surfaces come into contact with each other, the concave and convex portions are designed to mesh with each other. The shape of the contact portion 2 itself conforms to the outer shape of the connected members P1 and P2, and is not limited to a curved shape as shown in the drawing, but may be a square shape in some cases. It may be formed as a rectangular shape, a triangular shape, or the like corresponding to the outer shape of the connecting members P1 and P2.

In the drawing, it is considered that the holding pieces 3A and 3B themselves are reinforced by reinforcing edges formed by bending the peripheral portions of the holding pieces 3A and 3B inward, and bolt insertion holes are provided. 4 is not limited to the case where the hole is drilled in a circular shape as shown in the figure, but may be fitted to a bolt formed in a square root shape so as to prevent idling of a tightening bolt 11 of a fastening member 10 described later in some cases. May be formed in a rectangular shape.

[0012] A grip having left and right holding pieces 3A and 3B which are continuously provided in a mutually facing manner, and is provided in one of a pair of holding members 1A and 1B arranged adjacent to each other. For example, the inner holding piece 3A of the holding member 1A abutting on the inner holding piece 3A of the other holding member 1B.
And the fastening bolts 11 which are inserted and connected in common between the holding pieces 3A and 3B of the holding members 1A and 1B, respectively, and are fixed means Q such as welding by heat fusion such as arc welding or instant adhesive or the like. It is integrated by bonding or the like using a synthetic resin-curable adhesive. The fixing means Q is for preventing inadvertent relative rotation between the connected members P1 and P2. For example, when the fastening force of the holding member 1A is loosened by a nut-shaped knob 15A described later, Although the connected member P2 can be freely rotated around the connected member P1 as a rotation axis, the connected members P1, P
The two do not rotate in the direction in which they are folded. A ring-shaped stopper member 17 for supporting the holding member 1A is provided on the connected member P1 side on which the holding member 1A in which the holding piece 3A is integrated with the fastening bolt 11 by the fixing means Q is mounted. Is mounted so that the mounting position can be changed by, for example, loosening a plurality of holding screws (not shown) screwed into the peripheral side surface of the stopper member 17.

That is, the fastening member 10 is combined with the holding members 1A, 1B which are combined in a state where the outer surfaces of the inner holding pieces 3A facing each other of the holding members 1A, 1B are in contact with each other.
B are connected by tightening each other. Basically, any one of the holding members 1A, 1B is inserted into each of the bolt insertion holes 4 of the holding members 1A, 1B which match the holding pieces 3A, 3B.

B is provided with nut-shaped knobs 15A and 15B respectively screwed to both ends of the tightening bolt 11 protruding from B, and tightens the pair of holding members 1A and 1B respectively mounted on the connected members P1 and P2. Things. At this time,
The nut-shaped knob 15A is mounted on the side of the holding member 1A on which the holding piece 3A is integrated with the tightening bolt 11 by the fixing means Q, and the nut-shaped knob 15B is not provided with the fixing means Q, that is, tightened. The holding piece 3A is attached to the bolt 11 on the side of the holding member 1B that is free. Therefore, nut-shaped knobs 15A, 15B
Each of the clamping members 1A and 1B is independent from each other in the operation of fastening the clamping members 1A and 1B. Even if the knob 15A is loosened, the tightening force of the clamping member 1B on the other nut-shaped knob 15B is not loosened. The nut-shaped knobs 15A and 15B are formed in the shape of a dial-type cap so that a direct rotation operation or the like by a finger can be easily performed. A washer 16 is interposed on the outer surface of the outer holding piece 3B of the holding members 1A and 1B with which the members 15A and 15B abut.

The fixing means Q is formed by previously screwing a contact nut member 6 having an annular flange portion protruding at one peripheral edge thereof into a tightening bolt 11, and holding the holding piece 3A to be fixed.
With the flange portion abutting and held on the inner side surface, the abutment nut member 6 itself is fixed so as to be sealed so that reinforcement by integration can be achieved. This contact nut material 6
Is used to increase the holding force of the holding piece 3A with respect to the tightening bolt 11 and to prevent inadvertent relative rotation between the connected members P1 and P2. 11 or one of the holding pieces 3A may be fixed by welding or an adhesive, or the fastening bolt 11 and the holding piece 3A may be directly fixed by welding or an adhesive without using the contact nut material 6. Of course, it may be possible. Although not shown, the periphery of the bolt insertion hole 4 of the holding piece 3A is cut and raised to form a cylindrical shape and a female screw is formed on the inner peripheral surface of the cylinder to omit the contact nut member 6. You can also. In short, this fixing means Q integrates the holding piece 3A and the tightening bolt 11 by welding, bonding or the like in combination with screwing, or directly by welding or bonding without screwing. The structure, shape, means, and the like for the integration are not particularly limited.

As another embodiment of the fixing means Q, as shown in FIG. 3, the two fixing nut members 6 screwed into the tightening bolts 11 fix the fixing member Q on one of the holding members 1A. By firmly holding the inner and outer surfaces of the holding piece 3A, the tightening bolt 11 and the holding piece 3A,
3B. Then, nut-shaped knobs 15A, 15 screwed to the tightening bolts 11
Instead of forming B in the form of a dial-type cap, a quick release type fastening handle 12 is provided so as to obtain easy and simple fastening operation. It is to be noted that the two contact nut members 6 held in contact with the inner and outer side surfaces of the holding piece 3A may be fixed by welding, an adhesive or the like, if necessary, or the contact nut member 6 itself may be included. May be fixed to either the fastening bolt 11 or the holding piece 3A by welding or an adhesive.

Further, as still another embodiment of the fixing means Q, as shown in FIG. 4, the opposing inner holding pieces 3A of the holding members 1A and 1B are in contact with each other via a non-slip portion 5. In this state, the two holding nut members 6 arranged inside the holding members 1A and 1B and screwed into the tightening bolts 11 hold the holding members 1A and 1B at the inner side where they are joined to each other. The clamping bolt 11 and the two clamping members 1A, 1B are firmly clamped between the pieces 3A.
Each holding piece 3A is fixed. In this case, each of the nut-shaped knobs 15A and 15B is
A and 1B are independent from each other in the tightening operation. For example, a nut-shaped knob mounted on the side of the holding member 1A on which the holding piece 3A is integrated with the tightening bolt 11 by the fixing means Q Even if the nut 15A is loosened, the tightening force of the holding member 1B on the other nut-shaped knob 15B is not loosened. In addition, the holding member 1
When the mutual angle adjustment is performed between the nuts A and 1B, the nut-shaped knobs 15A and 15B are sufficiently loosened, and then the two contact nut members 6 are loosened using a spanner tool, so that the clamping members 1A and 1B are held.
It is only necessary to adjust the intersection angle between B. After the angle adjustment, the two contact nut members 6 may be strongly tightened so as to sandwich the inner holding pieces 3A. If necessary, it may be fixed by welding, an adhesive, or the like in a state in which the two contact nut members 6 holding the holding pieces 3 </ b> A are sandwiched, or the contact nut members 6 themselves may be tightened by the fastening bolts 11 or It may be fixed to one of the holding pieces 3A by welding or an adhesive or the like, and in this case, the crossing and the connection state are fixed.

The periphery of the bolt insertion hole 4 is
A, 3B are slightly depressed inward, and other holding members 1
A, 1B when combined with the holding members 1A, 1B
A separation applying means such as a spring washer is provided at the center of the opposing outer surfaces of the holding pieces 3A so that the holding members 1A and 1B are resiliently urged to separate from each other between the opposing inside holding pieces 3A. A space for accommodating (not shown) may be formed. For example, the separation giving means
The fastening member 10 is made up of an appropriate number of spring washers that are slightly bent so that the fastening bolt 11 of the fastening member 10 is inserted.
Pieces 3A, 3B which are fastened and contacted by
The two members are separated from each other by the release of the fastening by the fastening member 10, and the holding members 1A and 1B can freely change the connection angle of each other. The separating means is not limited to a spring washer having a flexure as shown in the figure, but may be a coil spring or a leaf spring.

Next, an example of use of the present embodiment will be described. As shown in FIGS. 1 and 2, the bolt insertion holes 4 formed in the holding pieces 3A and 3B of the holding members 1A and 1B, respectively.
The fastening bolt 11 of the fastening member 10 inserted into the holding member 3 and the holding piece 3A inside the holding member 1A are previously fixedly formed by the fixing means Q. The clamping members 1A and 1B are clamped and mounted on the connected members P1 and P2 to be cross-coupled with each other, and the fastening bolt 11 fixed to the clamping piece 3A of the clamping member 1A is fixed to the right and left of the other clamping member 1B. Are inserted into the bolt insertion holes 4 of the holding pieces 3A and 3B, and the outer surfaces of the opposed inside holding pieces 3A of the holding members 1A and 1B abut against each other, thereby holding the holding members 1A and 1B.
Tightening handles 12 and nut-shaped knobs 15A and 15B at both ends of the fastening bolts 11 protruding outward.
It is screwed with it. At this time, the connected member P
1 and P2, the crossing angle of each of the connected members P1 and P2 so as to appropriately set the fastening angle, the fastening position, and the like.
The slide position of the fastening position and the like is adjusted.

When the position, angle or the like is changed after the setting, the fastening force of the fastening handle 12 of the fastening member 10 and the nut-shaped knobs 15A and 15B is released to slightly separate the holding pieces 3A and 3B from each other. The angle adjustment by the holding members 1A and 1B is performed as
What is necessary is just to adjust again to the optimum position by swinging each of the connected members P1 and P2 inside B and further by sliding or the like. In this case, the nut-shaped knobs 15A and 15B are independent of each other in the fastening operation of the holding members 1A and 1B by the fixing means Q. For example, the holding piece 3A is integrated with the fastening bolt 11 by the fixing means Q. Even if the nut-shaped knob 15A mounted on the side of the holding member 1A which is formed is loosened, the tightening force of the holding member 1B firmly tightened by the other nut-shaped knob 15B does not loosen. It is. That is, one connected member P1 is connected to the holding member 1A fixed to the fastening bolt 11 by the fixing means Q,
When connecting the other connected member P2 to the holding member 1B,
Even if the nut-shaped knob 15A of the holding member 1A is loosened, the fixing position of the holding member 1B with respect to the holding member 1A does not change. Therefore, even though the connected member P2 can rotate around the connected member P1, the connected member P2 itself does not rotate around the axis of the connected member P2, and the intersection angle with the connected member P1. Is not changed.

The cross-connecting device according to the present invention can be used for various purposes. For example, as shown in FIGS. 5 and 6, a table made of a synthetic resin such as an acrylic plate used by a wheelchair user himself in a wheelchair C. It can be incorporated and used as a component in the table support device H that supports the member L. That is, the support post P (P1), the support bar B (P2), and the mounting leg L are attached to the pole portion F of the vehicle body where the lower end of the armrest arm portion of the wheelchair C and the front small wheel are connected.
When the table support device H including the table member L having the number 1 is mounted, the pole portion F and the support post formed of a pipe material whose end is closed and subjected to a retaining process are provided. P, and a support post P and a support bar B formed of a pipe material whose end is closed and subjected to a retaining process.
B, it is cross-connected by the fastening member 10 and the like. At this time, especially in the case of a wheelchair user, the posture and the like of the wheelchair C when riding the wheelchair C are variously changed depending on the obstacle condition and the like. Since the support length of the post P and the like can be adjusted steplessly, the position of the table member L can be set smoothly and promptly corresponding to each of the different posture modes.

On the other hand, the mounting position can be changed so as to retreat to an appropriate position when unnecessary, or disassembled if necessary. In particular, when the wheelchair user gets in or out of the wheelchair C, the table member L itself becomes obstructive if it is in front, so for example, by loosening the nut-shaped knob 15A in FIG. By rotating the support bar B about P around the rotation axis, the table member L itself can be rotated and retracted from the front position to the side, and at this time, the load of the article placed on the surface of the table member L Is large, the table member L does not slide down. Since the ring-shaped stopper member 17 for supporting the holding member 1A is mounted on the connected member P1 side, even if the nut-shaped knob 15A is loosened, the connected member P2 does not slide down ( (See FIG. 5).

This use example is not limited to the use as a constituent member of the table support device H as shown in the figure, but may be used in various forms. For example, the table member L may be used as a pillow member, a jaw, or the like. It can be changed to a support member or the like. Furthermore, not only the related members and devices of the wheelchair C but also various general connected members P1, P2
Can also be used for cross-linking.

In the above embodiment, the case where two connected members P1 and P2 are cross-connected has been described. However, the case where three or more connected members P1 and P2 are cross-connected. Can be used as a configuration, in which case 3
What is necessary is just to combine at least two holding members 1A and 1B. In addition, it is sufficient that the non-slip portions 5 of the holding pieces 3A, 3B are formed at the contact portions of the holding pieces 3A, 3B which are in contact with each other, and need to be formed on all outer surfaces of the holding pieces 3A, 3B. Is not something.

[0024]

The present invention is configured as described above.
For this reason, various connected members P such as pipe materials and rod materials are used.
1 and P2 can be securely cross-connected and fixed with an extremely simple mechanism, and can be easily handled even by those who are weak in operations such as angle adjustment and position adjustment, and can be easily handled. When the tool itself is used as the table support device H for the wheelchair C, the table member L is only rotated and retracted in the horizontal direction so that the user does not inconvenience the user in and out of the wheelchair C. Can be prevented from falling down, etc., and the cross-connecting point between the connected members 1 and 2 can be reinforced. Further, this type of pipe material and rod material can be used not only as a component of the table support device H. It can also be used as a versatile member for cross connection.

That is, in the present invention, this is a grip-like shape having left and right holding pieces 3A and 3B which are continuously provided so as to face each other, and a pair of holding members 1 arranged adjacent to each other.
A, 1B, the other holding member 1
A, 1B, holding pieces 3A, 3B, and holding member 1
This is because the fastening bolts 11 of the fastening members 10 which are inserted and connected in common between the holding pieces 3A and 3B of the respective A and 1B are integrated by the fixing means Q. Cross connection, its cross connection angle,
The flexibility of position and the like, the sliding property, and the like are obtained, and the handling is easy. In particular, the cross connector itself is wheelchair C
Piece 3A integrated with fastening bolt 11 by fixing means Q when used as table support device H for
Is slightly loosened with respect to the connected member P1 on the side of the holding member 1A having the table member L.
It can be easily rotated and retracted to the side from the state located in front of the user. In this case, the fastening member 10
The clamping members 1A and 1B are independent of each other. For example, even if the clamping member 1A in which the clamping piece 3A is integrated with the clamping bolt 11 is loosened by the fixing means Q, the other clamping member 1B is clamped. Since the force does not loosen, the table member L itself can be rotated and retracted in the horizontal direction by loosening the holding member 1A, and the table member L itself can be prevented from falling down.

The fixing means Q is fixedly fixed inside and outside the holding piece 3A by the contact nut member 6 screwed into the tightening bolt 11 itself, welding the holding piece 3A and the tightening bolt 11, welding or holding The piece 3A and the tightening bolt 11 are fixed with a nut and welded, or the holding piece 3A and the tightening bolt 11 are fixed by bonding with an adhesive, or the holding piece 3A and the tightening bolt 11 are fixed with a nut and bonded with an adhesive Since the solidified member is formed, the connected members P1 and P2 and the holding members 1A and 1B can be integrated firmly after the relative positioning, and the holding members 1A and 1B are further fastened by the fastening member 10. In this case, the degree of reinforcement can be further improved.

The holding members 1A and 1B are connected to each other by the other holding members 1A and 1B in the holding members 1A and 1B, respectively.
Since the holding pieces 3A contacting with each other are integrated by the contact nut members 6 screwed into the fastening bolts 11 inside the holding members 1A and 1B, the connected members P1 and P2 are connected.
After the relative positioning of the holding member 1A and 1B, the contact nut member 6 is tightened and held, so that the integration of the holding piece 3A and the tightening bolt 11 can be strengthened, and the cross connection portion Reinforcement can be easily secured. For example, when the angle between the connected members P1 and P2 is adjusted, the holding members 1A and 1B are sufficiently loosened, and then the two contact nut members 6 are loosened using a spanner tool. After the angle is adjusted, the angle can be easily adjusted by strongly tightening both contact nut members 6 inward so as to sandwich the inner holding pieces 3A. In addition, the fastening of the holding members 1A and 1B by the fastening member 10 becomes independent from each other, and the adjustment can be performed by operating separately.

The holding members 1A, 1B are connected to the connected members P1,
The connected member P is attached to the end of the contact portion 2 that contacts the outer peripheral surface
A pair of left and right holding pieces 3A and 3B which are located on the sides of P1 and P2 and are opposed to each other are continuously provided. A bolt insertion hole 4 is formed in each of the holding pieces 3A and 3B, and a holding piece 3A is formed. , 3B
Since the non-slip portion 5 having a corrugated shape is formed on the outer side surface, even when a load is applied to each of the connected members P1 and P2, the crossing angle of the connected members P1 and P2 to be cross-connected does not fluctuate. The table member L is maintained in a stable state. For example, when used as a component of the table support device H that supports the table member L of the wheelchair C user, the table member L to which a considerable load is applied is stable. It can be firmly supported.

Since the ring-shaped stopper member 17 for supporting the holding member 1A is mounted on the connected member P1 so that the mounting position can be changed, the cross-connecting device itself is used as the table supporting device H for the wheelchair C. When used, the table member L itself does not slide down even if the fastening state of the holding member 1A with respect to the connected member P1 is slightly loosened.
